In August 2011, Atna entered into an agreement with Sprott obtaining a CAD $20 million credit facility in order to finance the cash portion of the Pinson Mine acquisition and to provide initial development capital for the project.

Under terms of the extension Sprott has waived a $2.5 million payment due February 29, 2012 which will now become due February 28, 2013. An additional $2.5 million payment will be due on May 31, 2013, with the final balance of $15 million due in August 2013. As consideration for extending the credit facility Atna will issue 618,556 common shares of Atna to Sprott.

"Sprott's decision to extend the credit facility is evidence of their overall support of Atna and belief in the Company's development efforts. We feel market conditions have also played a part in the decision by Sprott as Atna is trading at 52-week highs and has recently gained institutional analyst support", states James Hesketh, President & CEO.

Current development efforts at the Pinson Mine include the completion of 300 meters of secondary access currently underway and the bulk sampling of ore. Additionally, Atna recently announced on February 6, 2012 a new resource estimate for the project.
